As per Kontera policies, we cannot use intext ads of any other ad network if we are monetizing with Kontera. This applies not just to this site, but to monetization of your personal blogs/websites too. You can use either Kontera or Infolinks intext ads.

Besides, if you see the Techlator page where we select the ad network we wish to incorporate, we can select only one of the options provided.

It is not possible to use both Kontera and Infolinks at the same time in techulator. I think Infolinks is more profitable than Kontera/Amobee Ads. That's why webmasters decided to offer Infolinks revenue in techulator, I guess.
